[S390] css: update descriptor after hibernate

Update the channel path descriptors after hibernation.
This is done unlocked, since we are the only active
task at this time.

Note: chsc_determine_base_channel_path_desc is changed
to use spin_lock_irqsave, since it's called with
interrupts disabled in this case.
